I have a 24-speed mountain bike with a pair of semi-slicks. I usually leave the big gear at 2 and the small gear I shift between 4 and 7. So I'm going along easy pedalling away on my local bike path when another mountain biker blows by me. Then I see that he's pedalling at half the speed that I'm pedalling and he's really pulling away from me. I shift the small gear to 8 (maximum) and my pedalling speed slows down and I'm picking up some distance but the guy is still pedalling slower than me and still pulling away from me at the same time.
I want to know how he does it. I want to pedal less and gain more distance. I want to be efficient too.
